FIGS. 1 and 2 schematically illustrate configuration of a display deviceaccording to an exemplary embodiment of the invention.

As shown in FIGS. 1 and 2, a display device 10 according to theembodiment of the invention may include a display module 100M and a backcover 120, which is positioned in the rear of the display module 100Mand is connected to the display module 100M.

Preferably, as shown in FIG. 2, the back cover 120 may be connected tothe display module 100M in a sliding manner in a direction (i.e., thesecond direction DR2) from the first long side LS1 to the second longside LS2.

In other words, the back cover 120 may be inserted into a first shortside SS1, a second short side SS2 opposite the first short side SS1, anda first long side LS1, which is adjacent to the first and second shortsides SS1 and SS2 and is positioned between the first short side SS1 andthe second short side SS2, of the display module 100M in the slidingmanner.

Although not shown, the back cover 120 may include a first protrusionextending toward a second side area opposite a first side area at an endof the first side area, a second protrusion extending toward the firstside area at an end of the second side area, and a third protrusionextending toward a fourth side area, which is adjacent to the first sidearea and the second side area and is opposite to a third side area, atan end of the third side area adjacent to the first side area and thesecond side area, so as to connect the back cover 120 to the displaymodule 100M in the sliding manner as described above.

The display module 100M may include a first connector corresponding tothe first protrusion, a second connector corresponding to the secondprotrusion, and a third connector corresponding to the third protrusion.

The configuration of the display device is described in detail below.

FIGS. 3 to 42 illustrate in detail configuration of a display deviceaccording to the embodiment of the invention. In the followingdescription, the descriptions of the configuration and the structuredescribed above may be omitted.

As shown in FIG. 3, a display device 10 according to the embodiment ofthe invention may a display module 100M including a display panel 100, afixer 300, and a guide panel 200, and a back cover 120.

The display module 100M may further include a frame 1000 which ispositioned in the rear of the display panel 100 and is connected to theguide panel 200. The frame 1000 may be positioned between the displaypanel 100 and the back cover 120.

The embodiment of the invention describes that the display module 100Mincludes the display panel 100, the fixer 300, and the guide panel 200.However, the display module 100M may further include an optical layer, alight source, and/or a top case.

The display panel 100 displaying an image may include a front substrateand a back substrate, which are positioned opposite each other. Thefixer 300 may be attached to a non-display area of a back surface of theback substrate of the display panel 100.

The back cover 120 may be connected to the guide panel 200.

Although not shown, the back cover 120 may protect various componentspositioned between the back cover 120 and the display panel 100.

The fixer 300 may be attached to a back surface of the display panel 100using an adhesive layer. More specifically, the fixer 300 may beattached to the back surface of the back substrate of the display panel100 using the adhesive layer.

The plurality of fixers 300 may be attached to the back surface of thedisplay panel 100. For example, at least one fixer 300 may be attachedto the back surface of the display panel 100 on a first long side LS1, afirst short side SS1, and a second short side SS2 of the display panel100.

The guide panel 200 may cover the fixer 300 and may be connected to thefixer 300.

The guide panel 200 may be positioned at an edge of the back surface ofthe display panel 100.

The guide panel 200 may include a first guide panel 210 corresponding toa first side area (i.e., the first short side SS1) of the display panel100, a second guide panel 220 corresponding to a second side area (i.e.,the second short side SS2) of the display panel 100, and a third guidepanel 230 corresponding to a third side area (i.e., the first long sideLS1) of the display panel 100. It may be preferable, but not required,that the first guide panel 210, the second guide panel 220, and thethird guide panel 230 form one body.

The guide panel 200 may include a resin material and a glass fibermaterial, so as to improve rigidity. This will be described in detaillater.

As shown in FIG. 4, the fixer 300 may include a base part 310 includinga groove 350, to which an adhesive layer is applied, a connector 320extending from the base part 310 in a vertical direction (i.e., a thirddirection DR3), and a head part 330 extending from an end of theconnector 320 in a horizontal direction (i.e., a first direction DR1and/or a second direction DR2) perpendicular to the vertical direction.

More specifically, the groove 350 may be formed at a first surface ofthe base part 310, and the connector 320 may extend from a secondsurface opposite the first surface in the vertical direction (i.e., thethird direction DR3).

The connector 320 may have an opening 340.

As shown in FIG. 5, an adhesive layer 360 may be formed between thefixer 300 and a back substrate 102 of the display panel 100. Hence, thefixer 300 may be attached to a back surface of the back substrate 102 ofthe display panel 100. Preferably, the adhesive layer 360 may be formedon the groove 350 of the base part 310 of the fixer 300.

As described above, when the fixer 300 is attached to the back surfaceof the back substrate 102 using the adhesive layer 360, a supporter,such as a pem nut and a boss, and a fastening member, such as a screw,are not used to fasten the fixer 300 to the back substrate 102.Therefore, a fixing process may be simply performed, the manufacturingcost may be reduced, and a thickness of the display device 10 may bereduced.

The display panel 100 may include a front substrate 101 and the backsubstrate 102, which are positioned opposite each other and are attachedto each other to form a uniform cell gap therebetween. A liquid crystallayer (not shown) may be formed between the front substrate 101 and theback substrate 102.

A seal part may be formed between the front substrate 101 and the backsubstrate 102 to seal the liquid crystal layer.

A color filter may be positioned on the front substrate 101 to implementred, green, and blue colors.

The color filter may include a plurality of pixels each including red,green, and blue subpixels. When light is incident on the color filter,the color filter may generate images corresponding to the red, green, orblue color.

A predetermined transistor, for example, a thin film transistor (TFT)may be formed on the back substrate 102. The transistor may turn on oroff liquid crystals in each pixel. In this instance, the front substrate101 may be referred to as a color filter substrate, and the backsubstrate 102 may be referred to as a TFT substrate.

The liquid crystal layer may include a plurality of liquid crystalmolecules, and the arrangement of the liquid crystal molecules maychange by a driving signal supplied by the transistor. Hence, lightprovided by a backlight unit (not shown) may be incident on the colorfilter based on changes in the arrangement of the liquid crystalmolecules of the liquid crystal layer.

As a result, the color filter may implement red, green, and blue light,and thus a predetermined image may be displayed on the front substrate101 of the display panel 100.

Since the above-described structure and configuration of the displaypanel 100 are merely an example, they may be changed, added, or omitted.

As shown in FIG. 6, the display panel 100 may further include a frontpolarizing film 500 and a back polarizing film 510. For example, thefront polarizing film 500 for polarizing light passing through thedisplay panel 100 may be disposed on a front surface of the frontsubstrate 101, and the back polarizing film 510 for polarizing lightpassing through the optical layer positioned in the rear of the backsubstrate 102 may be disposed on the back surface of the back substrate102.

The back polarizing film 510 may be separated from the fixer 300 by apredetermined distance D1 in the horizontal direction (i.e., the firstdirection DR1 and/or the second direction DR2).

The front polarizing film 500 may overlap the fixer 300 in the verticaldirection (i.e., the third direction DR3).

As shown in FIG. 7, the head part 330 may extend from the connector 320in the horizontal direction (i.e., the first direction DR1 and/or thesecond direction DR2) far from the center of the display panel 100.

Alternatively, as shown in FIG. 5, the head part 330 may extend from theconnector 320 toward the center of the display panel 100 in thehorizontal direction (i.e., the first direction DR1 and/or the seconddirection DR2).

Further, although not shown, the base part 310 of the fixer 300 may nothave the groove 350. In this instance, the adhesive layer 360 may beformed on the bottom of the base part 310.

As shown in FIG. 8, the display panel 100 may further include a resinlayer 600 formed on the side of the front substrate 101 and/or the sideof the back substrate 102.

The resin layer 600 may protect the side of the front substrate 101and/or the back substrate 102 of the display panel 100 from an impact.

As shown in (A) and (B) of FIG. 9, the guide panel 200 (i.e., a crosssection of the guide panel 200) may extend in the horizontal direction(i.e., the first direction DR1 and/or the second direction DR2) and mayinclude a first groove 710, into which the fixer 300 is inserted.

For example, the guide panel 200 may include a side wall SW extending inthe vertical direction (i.e., the third direction DR3), a firstextension EXP1 extending from the side wall SW in the horizontaldirection (i.e., the first direction DR1 and/or the second directionDR2), a second extension EXP2 extending from the first extension EXP1 inthe vertical direction (i.e., the third direction DR3), and a thirdextension EXP3 extending from the second extension EXP2 in thehorizontal direction (i.e., the first direction DR1 and/or the seconddirection DR2).

The side wall SW, the first extension EXP1, and the second extensionEXP2 of the guide panel 200 may form the first groove 710.

A first protuberance 700 extending in the horizontal direction (i.e.,the first direction DR1 and/or the second direction DR2) may be formedon an inner surface of the first groove 710 of the guide panel 200. Thefirst protuberance 700 may be used to connect the guide panel 200 to thefixer 300.

As shown in FIG. 10, the guide panel 200 may further include a secondgroove 720 extending in the horizontal direction (i.e., the firstdirection DR1 and/or the second direction DR2). A pad (not shown) may bedisposed on the second groove 720. The pad will be described later,

As described above, when the guide panel 200 includes the first groove710, the fixer 300 may be connected to the guide panel 200 in thesliding manner.

For example, as shown in FIG. 11, at least one fixer 300 may be disposedon each of the first short side SS1 and the second short side SS2 of thedisplay panel 100. Further, the guide panel 200 may be connected to thefixer 300 in the second direction DR2 of the horizontal direction in thesliding manner.

In such a manner, as shown in FIGS. 12 and 13, the fixer 300 may move inthe horizontal direction (i.e., the first direction DR1 and/or thesecond direction DR2) in a state where the fixer 300 is inserted intothe first groove 710 of the guide panel 200. Hence, as shown in FIGS. 13and 14, as the first protuberance 700 is inserted into a space betweenthe base part 310 and the head part 330 of the fixer 300, the fixer 300may be connected to the guide panel 200 in the sliding manner.

As shown in FIG. 14, the first protuberance 700 of the guide panel 200may extend from the second extension EXP2 in the horizontal direction(i.e., the first direction DR1 and/or the second direction DR2).

Further, a pad 800 having elasticity may be disposed between the guidepanel 200 and the back surface of the display panel 100. Preferably, thepad 800 may be disposed at a location corresponding to the second groove720 of the guide panel 200.

The guide panel 200 may cover the fixer 300 in a state where the guidepanel 200 and the fixer 300 are connected to each other.

As shown in FIG. 15, at least one fixer 300 may be disposed on the firstlong side LS1 of the display panel 100.

Further, the guide panel 200 may include the first guide panel 210corresponding to the first short side SS1 of the display panel 100, thesecond guide panel 220 corresponding to the second short side SS2 of thedisplay panel 100, and the third guide panel 230 corresponding to thefirst long side LS1 of the display panel 100. The first, second, andthird guide panels 210, 220, and 230 may form one body.

In this instance, it may be preferable, but not required, that the thirdguide panel 230 has an opening 201, so as to connect the fixer 300disposed on the first long side LS1 of the display panel 100 to thethird guide panel 230.

As shown in (A) of FIG. 16, the fixers 300 disposed on the first shortside SS1 and the second short side SS2 of the display panel 100 may beinserted into the first grooves 710 of the first and second guide panels210 and 220.

Next, as shown in (B) of FIG. 16, when the guide panel 200 is pushed up,the fixer 300 disposed on the first long side LS1 of the display panel100 may pass through the opening 201 formed on the side wall SW of thethird guide panel 230.

Afterwards, the opening 201 may be covered using a cover 1100. Namely,the cover 1100 may cover the opening 201.

As shown in FIG. 17, when the fixer 300 disposed on the first long sideLS1 of the display panel 100 passes through the opening 201 formed inthe side wall SW of the third guide panel 230, the first protuberance700 formed on an inner surface of the first groove 710 may be insertedinto a space between the base part 310 and the head part 330 of thefixer 300.

Alternatively, the first protuberance 700 may be inserted into anopening 340 formed in the connector 320 of the fixer 300. For this, alength of the first protuberance 700 of the third guide panel 230 in thehorizontal direction (i.e., the first direction DR1 and/or the seconddirection DR2) may be longer than lengths of the first protuberances 700of the first and second guide panels 210 and 220 in the horizontaldirection (i.e., the first direction DR1 and/or the second directionDR2).

As shown in FIG. 18, the head part 330 of the fixer 300 may extend fromthe connector 320 in the horizontal direction (i.e., the first directionDR1 and/or the second direction DR2) far from the center of the displaypanel 100, so as to easily insert the first protuberance 700 of thethird guide panel 230 into the opening 340 of the fixer 300.

In this instance, even if the length of the first protuberance 700 ofthe third guide panel 230 is relatively short, the first protuberance700 of the third guide panel 230 may be easily inserted into the opening340 of the fixer 300.

In this instance, the first protuberance 700 of the third guide panel230 may protrude from the inner surface of the first groove 710 in thedirection far from the center of the display panel 100. For example, thefirst protuberance 700 of the third guide panel 230 may protrude fromthe second extension EXP2 of the third guide panel 230 in the directionfar from the center of the display panel 100.

As shown in FIG. 19, the first protuberances 700 of the first and secondguide panels 210 and 220 may protrude in the direction toward the centerof the display panel 100. For example, the first protuberances 700 ofthe first and second guide panels 210 and 220 may protrude from the sidewalls SW of the first and second guide panels 210 and 220 in thedirection toward the center of the display panel 100.

In this instance, the fixers 300 disposed on the first and second shortsides SS1 and SS2 of the display panel 100 may be easily connected tothe first and second guide panels 210 and 220 in the sliding manner.

As shown in FIG. 20, an adhesive layer 800 for attaching the guide panel200 to the back surface of the display panel 100 may include a baselayer 810, a first layer 820 which is formed on a first surface FS ofthe base layer 810 and has the adhesion, and a second layer 830 which isformed on a second surface RS of the base layer 810 and has theadhesion.

It may be preferable, but not required, that the base layer 810 may beformed of a material having elasticity. For example, the base layer 810may be formed of urethane foam.

The adhesive layer 800 having the above-described configuration may havethe elasticity and the flexibility as well as the adhesion. Hence, theadhesive layer 800 may prevent an external force from being applied tothe guide panel 200 and thus may prevent the external force from beingtransferred to the display panel 100.

The adhesive layer 800 having the above-described configuration may bereferred to as a foam pad.

As shown in FIG. 21, the third guide panel 230 may include a thirdconnector 231. The third connector 231 may be formed on an externalsurface of the side wall SW of the third guide panel 230 and may be ahole or a groove formed toward the second long side LS2.

As shown in FIG. 22, the third connector 231 may be positioned betweenthe first grooves 710 corresponding to the fixers 300 on the side wallSW of the third guide panel 230.

As shown in FIG. 23, the back cover 120 may include a third protrusion1230 corresponding to the third connector 231.

The back cover 120 may include a main cover 120B, a first vertical part120V1 which extends from the main cover 120B and covers the externalsurface of the first guide panel 210, a second vertical part 120V2 whichextends from the main cover 1206 and covers the external surface of thesecond guide panel 220, and a third vertical part 120V3 which extendsfrom the main cover 120B and covers the external surface of the thirdguide panel 230.

The third protrusion 1230 may protrude from the third vertical part120V3 toward the second long side LS2. The third protrusion 1230 may beinserted into the third connector 231.

As shown in FIG. 24, an end of the third vertical part 120V3 of the backcover 120 may be formed by folding a portion of the back cover 120.

As shown in (A) of FIG. 50, the third connector 1730 of the frame 1000may include a third convex part protruding from a main body of the frame1000 toward the back cover 120. The third convex part may be formedusing a drawing method, etc. In the following description, the thirdconvex part may indicate the third connector 1730.

The third convex part 1730 may have a groove 1701 which is depressedtoward the second long side LS2.

In such a structure, the third protrusion 1230 of the back cover 120 maybe inserted into the groove 1701 of the third convex part 1730 in adirection from the first long side LS1 to the second long side LS2.

As shown in (B) of FIG. 50, the first connector 1710 of the frame 1000may include a first convex part protruding from the frame 1000 towardthe back cover 120, and the second connector 1720 of the frame 1000 mayinclude a second convex part protruding from the frame 1000 toward theback cover 120.

An example of a method for forming the first, second, and thirdconnectors 1710, 1720, and 1730 is described below.

As shown in FIG. 51, a first area AR1 corresponding to the first,second, and third convex parts is determined at a boundary of the secondhorizontal frame part 1020 and the inclined frame part 1030 of the frame1000.

An opening 1051 corresponding to the first, second, and third convexparts is formed in the third horizontal frame part 1050.

Next, as shown in FIG. 52, the first area AR1 may protrude using thedrawing method, etc.

Hence, at least one of the first and second convex parts may overlap atleast one of the second horizontal frame part 1020 and the inclinedframe part 1030 of the frame 1000.

Afterwards, as shown in FIGS. 50 and 53, when the frame 1000 is foldedalong a first folding line FL1 and a second folding line FL2, the first,second, and third convex parts may be exposed through the opening 1051of the third horizontal frame part 1050. Namely, the first, second, andthird connectors 1710, 1720, and 1730 may pass through the opening 1051of the third horizontal frame part 1050 and may be exposed.

As shown in FIG. 53, the first and second connectors 1710 and 1720 mayprotrude further than the third horizontal frame part 1050 by apredetermined height Y1. For this, it may be preferable, but notrequired, that a distance T10 between the first horizontal frame part1010 and the second horizontal frame part 1020 in the vertical direction(i.e., the third direction DR3) is longer than a distance T20 betweenthe second horizontal frame part 1020 and the third horizontal framepart 1050 in the vertical direction (i.e., the third direction DR3).

In this instance, the first and second protrusions 1210 and 1220 of theback cover 120 may be easily connected to the first and secondconnectors 1710 and 1720.

In such a structure, the first protrusion 1210 of the back cover 120 maybe inserted into the groove 1711 of the first connector 1710 in thedirection from the first long side LS1 to the second long side LS2 inthe sliding manner. Further, the second protrusion 1220 of the backcover 120 may be inserted into the groove 1721 of the second connector1720 in the direction from the first long side LS1 to the second longside LS2 in the sliding manner.

As a result, as shown in FIG. 54, the first protrusion 1210 may beengaged with the first connector 1710, and the second protrusion 1220may be engaged with the second connector 1720.

As shown in FIG. 55, the third protrusion 1230 may be formed at an end(i.e., an end of the first long side LS1) of the back cover 120. Thethird protrusion 1230 may be inserted into the groove 1701 of the thirdconnector 1730 (i.e., the third convex part) in the direction from thefirst long side LS1 to the second long side LS2.

Further, the fact that the side of the display panel 100 is exposed maymean that a resin layer 600 formed on the side of the front substrate101 and/or the side of the back substrate 102 of the display panel 100is exposed.

The guide panel 200 may be covered by the display panel 100. Namely, theguide panel 200 may be positioned in the rear of the display panel 100.In this instance, a visual effect, in which a bezel area of the displaydevice 10 seems to be smaller than its original size, may be obtained.

An external surface EXTS of the guide panel 200 may be exposed. In otherwords, the external surface EXTS of the side wall SW of the guide panel200 may be exposed.

In this instance, as shown in FIGS. 58 and 59, the guide panel 200 mayform an appearance of the side of the display device 10. Hence, thethickness of the display device 10 may be further reduced, and the sizeof the bezel area may be further reduced.

As described above, when the guide panel 200 forms the edge of thedisplay device 10, it may be preferable, but not required, that theguide panel 200 has the sufficiently large rigidity.

The guide panel 200 may include a resin material and a glass fibermaterial, so as to improve the rigidity of the guide panel 200.

It may be preferable, but not required, that the guide panel 200 furtherincludes a pigment material so as to improve the appearance of thedisplay device 10.

The guide panel 200 may be formed by mixing the resin material, theglass fiber material, and the pigment material, pouring a mixture in amold, and hardening the mixture. A content of the glass fiber materialmay be about 20 to 40 part by weight based on total weight of themixture, so as to sufficiently secure the rigidity of the guide panel200.

In this instance, even if the side wall of the guide panel 200 isrelatively thin, the rigidity of the guide panel 200 may be sufficientlysecured.

When the guide panel 200 includes the pigment material, a color of theguide panel 200 may be changed. It may be advantageous in terms of thedesign of the display device 10.

The inner wall 2020 may extend from the upper surface S2 of the basepart 2000 in the vertical direction (i.e., the third direction DR3).

The side wall 2010 may include a forward part 2012 extending forwardfrom the base part 2000 in the vertical direction (i.e., the thirddirection DR3) and a backward part 2011 extending backward from the basepart 2000 in the vertical direction (i.e., the third direction DR3).

A length W4 of the backward part 2011 may be longer than a length W5 ofthe forward part 2012.

Further, the length W4 of the backward part 2011 of the side wall 2010may be longer than a length of the inner wall 2020 by a predeterminedlength W3.

The first end E1 of the side wall 2010 is one end of the backward part2011, and the second end E2 of the side wall 2010 is one end of theforward part 2012. Further, the other end of the backward part 2011 ofthe side wall 2010 and the other end of the forward part 2012 may beconnected to each other.

As shown in FIG. 66, the optical layer 110 may be disposed on the basepart 2000 of the guide panel 200. More specifically, the optical layer110 may be disposed on the convex part 2001 of the base part 2000 of theguide panel 200.

The convex part 2001 may reduce an area of a contact surface between theoptical layer 110 and the guide panel 200.

The frame 1000 may be disposed on the inner wall 2020 of the guide panel200.

Further, the frame 1000 may be connected to the side wall 2010 of theguide panel 200 using a predetermined fastening member S500.

At least one connection hole may be formed in the side of the top case130 to connect the top case 130 with the back cover 120. For example, asshown in FIG. 67, a first connection hole 1900 may be formed in thethird parts 1820 of the first and second top cases 131 and 132.

The first connection hole 1900 may correspond to the first and secondprotrusions 1210 and 1220 of the back cover 120.

The first and second protrusions 1210 and 1220 may be inserted into thefirst connection hole 1900.

Alternatively, as shown in FIG. 68, a second connection hole 1910 may beformed in the fifth part 1850 of the third top case 133.

The second connection hole 1910 may correspond to the third protrusion1230 of the back cover 120.

The third protrusion 1230 may be inserted into the second connectionhole 1910.

More specifically, the third protrusion 1230 may be inserted into thesecond connection hole 1910 in the vertical direction (i.e., the thirddirection DR3).

As shown in FIG. 69, an overlap hole 2200 corresponding to the secondconnection hole 1910 may be formed in the side wall of the guide panel200. For example, the overlap hole 2200 may be formed in the side wallof the third guide panel 230.

In this instance, the third protrusion 1230 may sequentially passthrough the second connection hole 1910 and the overlap hole 2200.

As shown in FIG. 70, the first and second protrusions 1210 and 1220 maybe formed by folding the end of the back cover 120.

The second protrusion 1220 may include a second main protrusion 1221extending from an end of the second vertical part 120V2 toward the firstvertical part 120V1 and a second auxiliary protrusion 1222 extendingfrom the second main protrusion 1221 in the vertical direction (i.e.,the third direction DR3).

The second auxiliary protrusion 1222 may further include a portionextending further than the second main protrusion 1221 in a directionfrom the first long side LS1 to the second long side LS2. Hence, alength X2 of the second auxiliary protrusion 1222 may be longer than alength X1 of the second main protrusion 1221.

Further, the first auxiliary protrusion 1212 may further include aportion extending further than the first main protrusion 1211 in adirection from the first long side LS1 to the second long side LS2.Hence, a length X2 of the first auxiliary protrusion 1212 may be longerthan a length X1 of the first main protrusion 1211.

As shown in FIG. 71, the top case 130 may be connected to the guidepanel 200.

Alternatively, the top case 130 may be connected to the frame 1000.

For example, a predetermined fastening member S510 may fasten the fifthpart 1850 of the top case 130, the side wall SW of the guide panel 200,and the frame 1000 together.

A method for connecting the first and second protrusions 1210 and 1220of the back cover 120 to the first connection hole 1900 is describedbelow.

As shown in (A) of FIG. 72, the first and second protrusions 1210 and1220 may be inserted into the first connection holes 1900 of the firstand second top cases 131 and 132 in the vertical direction (i.e., thethird direction DR3).

Afterwards, as shown in (B) of FIG. 72, the first and second protrusions1210 and 1220 may slidingly move in the second direction DR2 in a statewhere the first and second protrusions 1210 and 1220 are inserted intothe first connection hole 1900.

As a result, as shown in (C) of FIG. 72, the first and secondprotrusions 1210 and 1220 may be engaged with the first connection hole1900.

As shown in FIG. 75, a display device 100 according to an exemplaryembodiment of the invention may include at least one of a display panel110, a guide panel 120, a backlight unit 130, a frame 140, and a backcover 150.

The display panel 110 may be the component displaying an image inresponse to a control signal of a controller. The display panel 110 mayinclude a plurality of layers. For example, the display panel 110 mayinclude a front substrate 114 and a back substrate 116.

The front substrate 114 and the back substrate 116 may substantiallyhave the same size. A seal portion for sealing a liquid crystal layermay be positioned between the front substrate 114 and the back substrate116. A protective plate 112 may be positioned on a front surface of thefront substrate 114.

The protective plate 112 may protect the display panel 110 from adamage, a scratch, etc. resulting from an external impact. Theprotective plate 112 may be substantially transparent. The protectiveplate 112 may be formed of a material having a strength and/or ahardness greater than the front substrate 114 and/or the back substrate116. The size of the protective plate 112 may be different from the sizeof the front substrate 114 and/or the back substrate 116. For example,an area of the protective plate 112 may be greater than an area of thefront substrate 114 and/or the back substrate 116.

The guide panel 120 may be positioned on the outer perimeter of thedisplay device 100. For example, the guide panel 120 may be coupled withthe side of at least one of the display panel 110, the backlight unit130, the frame 140, and the back cover 150. The guide panel 120 may beexposed to the outside through a front surface of the display device 100and/or the side of the display device 100. For example, the guide panel120 may form a bezel of the display device 100.

The guide panel 120 may be coupled with the display panel 110. Namely,the display panel 110 may be coupled with the display device 100 throughthe guide panel 120.

The backlight unit 130 may include a plurality of light sources. Thebacklight unit 130 may be classified into a direct type backlight unitand an edge type backlight unit depending on the disposition of thelight sources.

The backlight unit 130 may be coupled with a front surface of the frame140. For example, the plurality of light sources may be disposed on thefront surface of the frame 140. In this instance, the backlight unit maybe referred to as the direct type backlight unit.

The backlight unit 130 may include an optical sheet. The optical sheetmay diffuse light of the light sources. The optical sheet may include aplurality of layers. For example, the optical sheet may include at leastone prism sheet and/or at least one diffusion sheet.

The frame 140 may support the components of the display device 100. Forexample, the frame 140 may be coupled with the backlight unit 130. Theframe 140 may be formed of a metal material, for example, aluminumalloy.

The back cover 150 may be coupled with a back surface of the displaydevice 100. Namely, the back cover 150 may be coupled with the displaydevice 100 so as to shield the frame 140, etc. The back cover 150 may beslidingly coupled with the display device 100. Namely, a predeterminedstructure may be formed between the display device 100 and the backcover 150 so that the back cover 150 can be easily coupled with thedisplay device 100. The sliding coupling structure of the back cover 150and the display device 100 will be described in detail later.

FIGS. 76 to 84 illustrate a display panel of the display device shown inFIG. 75.

As shown in FIGS. 76 to 84, the display panel 110 of the display device100 according to the embodiment of the invention may include a resinportion 111 and/or a protective plate 112 for protecting the displaypanel 110.

As shown in FIG. 76, the resin portion 111 may be positioned on the sideof the display panel 110. For example, the resin portion 111 may bepositioned on the side of a substrate 117. The resin portion 111 may bepositioned on the side of a front substrate 114 and the side of a backsubstrate 116. The resin portion 111 may be positioned along at leastone of four edges of each of the front substrate 114 and the backsubstrate 116

The resin portion 111 may protect the display panel 110. The resinportion 111 may protect the display panel 110 from an impact appliedfrom the side of the display panel 110.

The resin portion 111 may have characteristic different from the displaypanel 110. For example, the resin portion 111 may be a material havingelasticity.

Thus, when an impact is applied to the resin portion 111, the resinportion 111 may be elastically deformed and may absorb the impact.

The resin portion 111 may include a plurality of layers. For example,the resin portion 111 may include a first resin portion 111 a directlycontacting the side of the substrate 117 and a second resin portion 111b positioned on the outer side of the first resin portion 111 a. Namely,the first and second resin portions 111 a and 111 b may be sequentiallystacked in a radial direction of the substrate 117.

The first and second resin portions 111 a and 111 b may have differentcharacteristics. Namely, it indicates that the first and second resinportions 111 a and 111 b may be formed of different materials. Forexample, the first resin portion 111 a may be a soft material softerthan the second resin portion 111 b. In other words, the first resinportion 111 a may be a material having a larger deformation degreeagainst an external force than the second resin portion 111 b. Thus,when the external force is applied to the side of the substrate 117, thefirst resin portion 111 a of the soft material may firstly absorb theexternal force, and then the second resin portion 111 b of a hardmaterial may absorb the remaining external force.

Each of the first and second resin portions 111 a and 111 b may have acolor. The first and second resin portions 111 a and 111 b may havedifferent colors. For example, the first resin portion 111 a may have abright color, and the second resin portion 111 b may have a dark color.In this instance, because the first resin portion 111 a of the brightcolor is conspicuous, the first resin portion 111 a may be the point interms of the design.

The protective plate 112 may be coupled with one side of the substrate117. For example, the protective plate 112 may be coupled with a frontsurface of the substrate 117.

The protective plate 112 may be formed of a material different from thesubstrate 117. For example, the protective plate 112 may be formed of amaterial harder than a material of the substrate 117. Thus, theprotective plate 112 may protect the substrate 117 from an impactapplied from the front.

The protective plate 112 may be larger than the substrate 117. Forexample, the protective plate 112 may include an extension EA protrudingfurther than the substrate 117 to the outside.

The extension EA of the protective plate 112 may contact the resinportion 111. For example, the first resin portion 111 a may contact boththe substrate 117 and the extension EA, and the second resin portion 111b may contact both the first resin portion 111 a and the extension EA.

The extension EA may protect the substrate 117 from the external impact.The extension EA may be configured so that the resin portion 111 can bestably coupled. Namely, the extension EA may increase an area to whichthe first and second resin portions 111 a and 111 b can be attached.

As shown in FIG. 77, another structure of the display panel 110according to the embodiment of the invention may be configured so thatthe resin portion 111 can be more efficiently attached. For example, thefront substrate 114 may have a first inclined surface 114 a, and theback substrate 116 may have a second inclined surface 116 a. Aplanarization portion 115 may be formed by the first and second inclinedsurfaces 114 a and 116 a at an upper part of the substrate 117. Acontact area between the substrate 117 and the resin portion 111 mayincrease due to the first and second inclined surfaces 114 a and 116 aand/or the planarization portion 115.

As shown in FIG. 78, another structure of the display panel 110according to the embodiment of the invention may be configured so thatthe front substrate 114 and the back substrate 116 respectively have afirst inclined surface 114 a and a second inclined surface 116 a.

As shown in FIGS. 79 and 80, another structure of the display panel 110according to the embodiment of the invention may be configured so thatlengths and/or areas of the front substrate 114 and the back substrate116 are different from each other.

More specifically, a length of the front substrate 114 may be longerthan a length of the back substrate 116 by ‘DF’. Alternatively, a lengthof the back substrate 116 may be longer than a length of the frontsubstrate 114 by a length DF.

When the lengths of the front substrate 114 and the back substrate 116are different from each other, contact areas between the front and backsubstrates 114 and 116 and the resin portion 111 may increase. Namely, acontact area and/or a contact length between the front substrate 114 orthe back substrate 116 and the resin portion 111 may increase by thelength DF of the side of the front substrate 114 or the side of the backsubstrate 116, compared to when the resin portion 111 contacts the uppersides of the front and back substrates 114 and 116.

As shown in FIG. 81, the first and second resin portions 111 a and 111 bmay be sequentially stacked on an outer area of the substrate 117.Namely, the first and second resin portions 111 a and 111 b may bepositioned along the outer perimeter of the display panel 110. It is amatter of course that at least one of the first and second resinportions 111 a and 111 b may be positioned only at a specific edge ofthe display panel 110. For example, at least one of the first and secondresin portions 111 a and 111 b may be provided only on the long sidecorresponding to the upper side of the display panel 110, which ishighly likely to receive an impact from the outside. The first andsecond resin portions 111 a and 111 b may substantially have the samethickness as the substrate 117.

As shown in FIG. 82, the resin portion 111 may protrude further than theprotective plate 112. For example, the resin portion 111 may protrudefurther than the protective plate 112 toward the outside by ‘HT’. Whenthe resin portion 111 protrudes toward the outside, the resin portion111 may more efficiently protect the display panel 110 from an impactfrom the outside. For example, when an external object approaches thedisplay panel 110 in a Y-axis direction, the external object may contactthe second resin portion 111 b earlier than other components of thedisplay panel 110. Hence, the second resin portion 111 b may protect thecomponents of the display panel 110, for example, the protective plate112.

As shown in FIGS. 83 and 84, the resin portion 111 and/or the protectiveplate 112 may be formed in accordance with a predetermined processorder.

As shown in (a) of FIG. 83, the protective plate 112 may be attached tothe front surface of the substrate 117. The protective plate 112 may begreater than a length and/or a width required in the completed displaypanel 110. For example, the protective plate 112 may be greater than thelength and/or the width required in the completed display panel 110 by‘MP’.

As shown in (b) of FIG. 83, after the protective plate 112 is attachedto the substrate 117, a portion of the outer side of the protectiveplate 112 may be processed. Namely, the margin MP of the protectiveplate 112 may be removed in accordance with the length and/or the widthrequired in the completed display panel 110.

The first resin portion 111 a may be formed when the protective plate112 is removed and/or before or after the protective plate 112 isremoved. For example, the first resin portion 111 a may be formed on theside of the substrate 117 by injecting a liquid or semiliquid resin.

As shown in (c) of FIG. 83, the second resin portion 111 b may beadditionally applied on the first resin portion 111 a. The upper side ofthe first resin portion 111 a and/or the second resin portion 111 b mayhave an oval shape because of the properties of the liquid or semiliquidresin. The second resin portion 111 b may protrude further than theprotective plate 112 toward the outside because of the oval upper sideof the second resin portion 111 b.

As shown in (a) of FIG. 84, the protective plate 112 may be attached tothe front surface of the substrate 117. The protective plate 112 may begreater than a length and/or a width required in the completed displaypanel 110.

As shown in (b) of FIG. 84, the first and second resin portions 111 aand 111 b may be applied before the protective plate 112 is processed.

As shown in (c) of FIG. 84, after the application of the first andsecond resin portions 111 a and 111 b is completed, the protective plate112 may be processed. Namely, a margin MP of the protective plate 112exceeding the length and/or the width required in the completed displaypanel 110 may be removed. A portion of the upper side of the secondresin portion 111 b may be removed in a process for removing theprotective plate 112. Thus, a height of the outer side of the protectiveplate 112 and a height of the upper side of the second resin portion 111b may be substantially the same as each other.

FIGS. 85 to 90 illustrate a structure of the display device shown inFIG. 75.

As shown in FIGS. 85 to 90, the display device 100 according to theembodiment of the invention may have a structure capable of preventingthe components of the display device 100 from being damaged by anexternal force.

As shown in FIG. 85, which shows a cross section of the display device100, the display panel 110 may be positioned at the front of the displaydevice 100, and the backlight unit 130 may be positioned in the rear ofthe display panel 110. Further, the frame 140 may be positioned in therear of the backlight unit 130, and the guide panel 120 may bepositioned on the side of the backlight unit 130.

One side of a support clip 145 may be fixed to the frame 140. Forexample, one end of a first support clip body 145 a of the support clip145 may be coupled with the frame 140. A second support clip body 145 bof the support clip 145 may be formed by bending the first support clipbody 145 a, and a third support clip body 145 c of the support clip 145may be formed by bending the second support clip body 145 b.

The second support clip body 145 b may contact the guide panel 120. Forexample, the second support clip body 145 b may come in surface contactwith the guide panel 120. A deformation of the guide panel 120 may beminimized due to the contact between the second support clip body 145 band the guide panel 120. For example, when the guide panel 120 isdeformed by the external force, the second support clip body 145 b maysupport the guide panel 120. Hence, the deformation of the guide panel120 may be minimized.

The second support clip body 145 b may be directly coupled with theguide panel 120. For example, an extension extending from a first guidepanel body 120 a of the guide panel 120 may be directly coupled with thesecond support clip body 145 b. The support clip 145 may be fixed at anoriginal position due to the coupling between the extension of the firstguide panel body 120 a and the second support clip body 145 b.

The third support clip body 145 c may be bent toward the frame 140. Anend of the third support clip body 145 c may be adjacent to or contact asecond frame body 140 b of the frame 140. Thus, when the guide panel 120is deformed by the external force, the end of the third support clipbody 145 c may contact the second frame body 140 b of the frame 140 andmay minimize the deformation of the guide panel 120.

A second guide panel body 120 b of the guide panel 120 may include astopper 120 c. The stopper 120 c may have a shape obtained by protrudinginward the second guide panel body 120 b. The stopper 120 c may beadjacent to or contact the back surface of the frame 140.

The stopper 120 c may prevent the deformation of the guide panel 120.

Alternatively, the stopper 120 c may prevent a predetermined amount ofthe deformation of the guide panel 120. For example, when the externalforce is applied downwards to the upper side of the guide panel 120, thedeformation of the guide panel 120 may be prevented due to the stopper120 c contacting the guide panel 120.

The second guide panel body 120 b of the guide panel 120 may furtherinclude a protrusion 120 d. The protrusion 120 d may have a shapeobtained by extending the second guide panel body 120 b to the inside.When the upper side of the frame 140 is coupled with the stopper 120 c,and the lower side of the frame 140 is coupled with the protrusion 120d, the deformation of the guide panel 120 resulting from the externalforce may be prevented.

The guide panel 120 may be positioned adjacent to the display panel 110.For example, a front end 120 e of the guide panel 120 may be positionedadjacent to the display panel 110 at a separation distance CDtherebetween. The separation distance CD between the front end 120 e ofthe guide panel 120 and the display panel 110 may be within severalmillimeters, so as to improve the design completeness. In this state,when the guide panel 120 is deformed by the external force, the frontend 120 e of the guide panel 120 may contact the display panel 110. Thesupport clip 145, the stopper 120 c, and/or the protrusion 120 d of thedisplay device 100 according to the embodiment of the invention mayprevent the deformation of the guide panel 120.

As shown in FIG. 86, an external force F may be applied to the guidepanel 120. When the external force F is applied, the guide panel 120 maybe deformed. As described above, the front end 120 e of the guide panel120 may be positioned adjacent to the display panel 110. Even when theexternal force F is applied to the guide panel 120, the contact betweenthe front end 120 e of the guide panel 120 and the display panel 110 maynot be generated. Namely, the deformation of the guide panel 120 may beprevented through the contact between the third support clip body 145 cof the support clip 145 and the second frame body 140 b of the frame140. Further, the deformation of the guide panel 120 may be preventedthrough the contact between the stopper 120 c of the guide panel 120 andthe second frame body 140 b of the frame 140.

As shown in FIG. 87, the resin portion 111 may be positioned at an endof the display panel 110. The resin portion 111 may include a pluralityof layers. Even when the guide panel 120 adjacent to the display panel110 is excessively deformed, the front end 120 e of the guide panel 120may contact not the back substrate 116 but the resin portion 111. Thus,a damage of the display panel 110 resulting from the deformation of theguide panel 120 may be prevented.

As shown in FIG. 88, the stopper 120 c and the protrusion 120 d may beadhered to the frame 140. For example, the second frame body 140 b maybe coupled between the stopper 120 c and the protrusion 120 d. At leastone of the stopper 120 c and the protrusion 120 d may be fixed to theframe 140 through a screw.

As shown in (a) of FIG. 89, a protrusion protruding in a direction fromthe guide panel 120 to the frame 140 may be provided. For example, aprotrusion 120 f protruding in a direction from the first guide panelbody 120 a to the second frame body 140 b and a contact portion 120 gextending from the protrusion 120 f may be formed.

The contact portion 120 g may contact the second frame body 140 b. Thus,even when the external force is applied to the guide panel 120, thecontact between the guide panel 120 and the display panel 110 may beprevented by the contact portion 120 g.

As shown in (b) of FIG. 89, the support clip 145 and the contact portion120 g may be provided. The third support clip body 145 c and the contactportion 120 g may contact the second frame body 140 b.

The guide panel 120 may have a fixed protrusion 120 h. The fixedprotrusion 120 h may contact the support clip 145. The fixed protrusion120 h may support the support clip 145 so that the support clip 145 isfixed at a given position.

As shown in (a) of FIG. 90, the support clip 145 may be coupled with theguide panel 120. Namely, the second support clip body 145 b may beinserted into first and second coupling protrusions 120 h and 120 iextending from the guide panel 120. Because the second support clip body145 b supports the first guide panel body 120 a, the deformation of theguide panel 120 may be prevented.

A third coupling protrusion 120 j may extend from the first couplingprotrusion 120 h toward the frame 140. The third coupling protrusion 120j may contact the frame 140. The deformation of the guide panel 120 maybe prevented by the third coupling protrusion 120 j contacting the frame140.

The flange 152 may include a first flange body 153 extending from theback cover 150 and a second flange body 155 which extends from the firstflange body 153 by bending inward the first flange body 153. The firstflange body 153 may contact the guide 142 coupled with the frame 140.This is described in detail later.

A state where the flange 152 contacts the guide 142 and the back cover150 is inclined at a predetermined angle may be referred to as a firststate. A state where a portion of the flange 152 is detached from theguide 142 and is substantially parallel with the frame 140 may bereferred to as a second state. Namely, the back cover 150 may move fromthe first state to the second state and may be coupled with the frame140.

As shown in FIG. 95, the guide 142 may have a structure which isconfigured so that the flange 152 of the back cover 150 is slidinglycoupled with the guide 142. For example, first to fourth guides 145,146, 147, and 148 may be formed.

At least one of the first to fourth guides 145, 146, 147, and 148 may berepeatedly formed along the long side of the frame 140. For example, thesecond, third, and fourth guides 146, 147, and 148 may be repeatedlyformed along the ling side of the frame 140. A set of the guides (forexample, 146, 147, and 148) which are repeatedly formed, may correspondto one flange 152 of the back cover 150. Each guide is described indetail below.

As shown in FIG. 96, a fifth guide 149 may be positioned on the frame140. The fifth guide 149 may have a cross shape.

The fifth guide 149 may include a 5 a guide 149 a and a 5 b guide 149 b.The 5 a and 5 b guides 149 a and 149 b may be separated from each otherat a predetermined distance therebetween.

The back cover 150 may include an extension 152 between slits 154. Theslit 154 may include first and second slits 154 a and 154 bcorresponding to the 5 a and 5 b guides 149 a and 149 b.

FIGS. 97 to 105 illustrate a sliding coupling process of the back cover150 using the above-described structure.

As shown in (a) of FIG. 97, a worker may approach the back cover 150 tothe frame 140. In this instance, the worker may dispose the slit 154 ofthe back cover 150 at a position corresponding to the fifth guide 149 ofthe frame 140.

As shown in (b) of FIG. 97, a vertical plate 149 bv of the fifth guide149 may be inserted into the slit 154 of the back cover 150. When thevertical plates 149 bv of the 5 a and 5 b guides 149 a and 149 b arerespectively inserted into the two slits 154, a coupling position of theback cover 150 in the x-axis direction may be naturally aligned.

The worker may insert the fifth guide 149 into the slit 154 and also maydispose a back surface of the back cover 150 on a horizontal plate 149bh of the fifth guide 149.

As shown in FIG. 98, when a bottom portion of the back cover 150 isinserted into the fifth guide 149, a predetermined angle ‘a’ between theback cover 150 and the frame 140 may be formed. Namely, the bottomportion of the back cover 150 may be close to the frame 140, and a topportion of the back cover 150 may be separated from the frame 140. Theback cover 150 may easily slide in a detachment direction due to such adisposition of the back cover 150.

As shown in FIG. 99, when the bottom portion of the back cover 150 isinserted into the fifth guide 149, the flange 152 of the back cover 150may be put up on the first guide 145.

The first guide 145 may include a body portion 145 b extending in az-axis direction and a base portion 145 a extending from the bodyportion 145 b. The base portion 145 a may be inclined at a predeterminedangle. In other words, the base portion 145 a may be formed at anoblique angle. Thus, a first flange 152 a may be naturally put up on thebase portion 145 a. Further, the back cover 150 connected to the firstflange 152 a may be slide on the base portion 145 a in an arrowdirection D1 shown in FIG. 99.

As shown in FIG. 100, at least one of the flanges 152 may be positionedon the fourth guide 148. For example, a second flange 152 b may be putup on a 4 a guide 148 a corresponding to the second flange 152 b.

As shown in (a) of FIG. 101, the back cover 150 may slide on the fourthguide 148 in the arrow direction D1 in a state where the flange 152 isput up on the fourth guide 148.

As shown in (b) of FIG. 101, the flange 152 sliding on the fourth guide148 may move under the fourth guide 148. For example, the second flange152 b moving up to an end of the 4 a guide 148 a may fall under the 4 aguide 148 a.

The flange 152 falling under the fourth guide 148 may contact the secondguide 146.

As shown in FIGS. 102 and 103, the second guide 146 may protrude inwardby ‘W’. Thus, the second guide 146 may pressurize the side of the flange152. For example, when the flange 152 moves from a P1 state to a P2state, the second guide 146 may contact the side of the flange 152. Whenthe flange 152 is pressurized by the second guide 146, a noise and/or avibration generated by the contact between the flange 152 and otherstructure may be prevented.

As shown in FIG. 104, when the flange 152 continuously slides in thedirection D1, the flange 152 may be inserted into an opening of thethird guide 147. The flange 152 inserted into the third guide 147 may becoupled with the third guide 147 and may be fixed to the third guide147.

As shown in (a) of FIG. 105, the back cover 150 and the frame 140 may becoupled with each other.

As shown in (b) of FIG. 105, a sixth guide 144 may be provided in a toparea of the frame 140, and a bending area 150 c may be provided at aposition corresponding to the back cover 150. The bending area 150 cbending inward may be coupled with the sixth guide 144 when the backcover 150 and the frame 140 are coupled with each other.

The sixth guide 144 may include a body portion 144 a and an end portion144 b extending from the body portion 144 a. The end portion 144 b maybe inclined upwardly. Thus, the bending area 150 c may naturally move tothe inside of the body portion 144 a along the end portion 144 b.
